Introduction
In general, kiwifruit cannot directly treat all types of oral ulcers. It only has an auxiliary improving effect on oral ulcers caused by vitamin C deficiency, and shows no significant therapeutic effect on ulcers resulting from other causes. In daily life, to prevent oral ulcers, it is important to maintain a balanced diet. In addition to moderately consuming fruits and vegetables rich in vitamins, one should also avoid spicy and excessively hot foods.
In general, kiwifruit cannot directly treat all types of oral ulcers. It only has an auxiliary improving effect on ulcers caused by vitamin C deficiency and shows no significant therapeutic effect on ulcers resulting from other causes. The detailed analysis is as follows:
Kiwifruit is rich in vitamin C. If oral ulcers are caused by a long-term dietary deficiency of this nutrient, leading to impaired healing capacity of the oral mucosa, consuming an appropriate amount of kiwifruit can help replenish vitamin C, enhance the mucosa's ability to repair itself, promote ulcer healing, and alleviate the fragility of the mucosa, thus providing supportive improvement.
However, if oral ulcers are triggered by other factors such as oral trauma, bacterial infection, high stress levels, or staying up late, kiwifruit cannot address these underlying causes and therefore does not have a therapeutic effect. In such cases, it merely serves as a regular fruit for nutritional supplementation. Moreover, excessive consumption may lead to irritation of the ulcerated area by the fruit's organic acids, potentially worsening pain and discomfort.
In daily life, preventing oral ulcers requires maintaining a balanced diet. In addition to moderately consuming fruits and vegetables rich in vitamins, one should also avoid spicy and excessively hot foods to reduce irritation to the oral mucosa.
